77. Solving a chemistry problem

2. What will be the value of the thermodynamic constant of chemical equilibrium for the reaction of obtaining a gaseous substance from simple substances at 298K and 500K with standard Gibbs energy measurements under the conditions given in the table?

Task: -85.3 ΔG298, KJ/mol; -75.5 ΔG500, KJ/mol

When solving this task, pay special attention to the fact that the value of the thermodynamic equilibrium constant of a chemical reaction can be calculated from the values of standard thermodynamic quantities given in the relevant reference books.
